Nice. I read that I can connect at 9600 to USART2 to read the debug information. So this should give enough to analyze the problem. Thanks for the pointer ventosus. </p> http://forums.leaflabs.com/topic.php?id=13395#post-28472 Thu, 15 Aug 2013 07:51:39 +0000 ventosus 28472@http://forums.leaflabs.com/ <p>Sounds like you're experiencing the LED throb. That's how libmaple tells you that a serious error happened, e.g. your sketch crashed by an invalid memory access, unsucessful ASSERT, ...</p> <p>The code you're looking for most probably is this one:<br /> <a href="https://github.com/leaflabs/libmaple/blob/master/libmaple/util.c" rel="nofollow">https://github.com/leaflabs/libmaple/blob/master/libmaple/util.c</a> </p> http://forums.leaflabs.com/topic.php?id=13395#post-28471 Thu, 15 Aug 2013 05:40:14 +0000 SevenW 28471@http://forums.leaflabs.com/ <p>Once in a while my Olimexino-STM32 does not properly boot after downloading a sketch. The green LED shows a pulsating flash about once per second. What does this error code mean, and what library generates this LED control?</p> <p>I searched SDFatLib, and spi files, but I cannot find any LED control in there.</p> <p>The LED gradually increases in intensity, and then decreases, like a dimmer sketch. </p> <p>It happens in a logger application, and it is related to the SDCard. When I take out the SDCard, reinsert it and press reset, it boots normally. When in this error state, no connection can be made with SerialUSB.</p> <p>Any thoughts?</p> <p>regards,<br /> SevenW </p>
